# V584\. Same value is present on both sides of the operator\. The expression is incorrect or can be simplified\.

Analyzer found an expression that can be simplified\. The possibility of a misprint presence in it is quite high\.

Let's review an example:

```cpp
float SizeZ;
if (SizeZ + 1 < SizeZ)
```

The analyzer thinks that this condition contains a mistake because it is practically senseless\. Most likely another check was implied\. The correct variant:

```cpp
if (SizeZ + 1 < maxSizeZ)
```

Of course programmers sometimes utilize some tricks which are formally correct but do appear quite odd\. The analyzer tries to detect such situations if possible and not to produce warnings\. For instance the analyzer considers such checks as being safe: 

```cpp
//overflow test for summation
int a, b;
if (a + b < a)

//Verifying that x does not equals zero, +infinity, -infinity
double X;
if (X * 0.5f != X)
```
